Abstract
Various kinds of ships(cargo ship, passenger ship, training ship, and special ship) are operated to transport cargo or passengers at sea in the world. Most of the important auxiliary machinery installed in those ships is fluid machinery such as pump, compressor, and fan. A large percentage of fluid machinery is pumps which are classified turbo and positive displacement pump type. While many previous researches have focused on pumps for shore use, very few are known about marine use pump.

This thesis has two aims: (a) to analyze the present status of pumps installed in merchant and training ships, (b) to contribute to the development of educational material and foundation of research about ship's pump, (c) to find the correlation among sea going pump kW, port pump kW, total pump kW, GE kW, ME MCR, number of pumps, DWT, ME kgf, pump kgf.



Based on ship's type, my paper seeks to classify turbo type pump and positive displacement type pump and to find special characteristics as a result of analyzing head, flow rate, and kW.

Moreover this paper analyzes and compares number of pumps, rpm of pumps, pump kW/ME MCR, pump kW/GE kW under the conditions of seagoing and berthing according to ship's type. It then focuses on how two results(merchant ships, training ships) are analogous.

The author further shows that training ships are compatible to train cadets who will onboard various kinds of ships about pumps.



Divided into five chapters, this dissertation uses marine use pumps as basic tool for the study.

Chapter I presents the research design, background, and purpose.

Chapter II portrays the status of pumps installed in ship.

Chapter III examines the data analysis, explains and interprets the data tables and basic results of the study which is the present status of pumps installed in various kinds of ships.

Chapter IV analyzes correlation coefficient of various values.

Chapter V provides results of the study.



Finally, it seems legitimate to conclude from all this that

The author describes and analyzes the status of pumps installed in ships using graphs.

1) the highest head: boiler feed water pump, boiler F.O. service pump.

2) the majority of turbo type pump rpm is 1,800 rpm and positive displacement type is 1,200 rpm.

3) number of pumps of turbo and positive displacement type:

diesel engine => nearly same number.

turbine engine =>the number of turbo type pumps are much more than the number of positive displacement pumps.

The author finds the result of correlation is as follows
ME weight - total pump kW: 0.156



This paper's main contribution is to be used as a educational material and foundation of research about ship's pump.
ME weight - number of pumps: 0.12


ME weight - port pump kW: 0.099


ME weight - pump weight:-0.054


DWT - ME weight: -0.032


2) correlation coefficient of various values(low rank 5)


ME weight - ME MCR: 0.900


pump weight - DWT: 0.905


pump weight - total pump kW: 0.924


GE kW - seagoing pump kW: 0.934


Total pump kW - port pump kW: 0.993


1) correlation coefficient of various values(high rank 5)
